Version History

The version history of the metadata syntax is given below.

0.15 - 2019-11-05

Added

  • The condition function is_master(file_path path), which checks if the given file is an installed master plugin.

0.14 - 2018-12-09

Added

  • The Group data structure now has a description key that takes a string value.

  • The condition function product_version(file_path path, version given_version, comparison_operator comparator), which checks against the Product Version field of an executable.

Changed

  • clean and dirty metadata are now allowed in regex plugin entries.

  • Location, Message, MessageContent and Tag equality comparisons are now case-sensitive.

  • Regular expressions in condition strings now use a modified Perl grammar instead of a modified ECMAScript grammar. Plugin object name fields still use the modified ECMAScript grammar for regex values. To improve portability and avoid mistakes, it’s best to stick to using the subset of regular expression features that are common to both grammars.

Removed

  • The change in regular expression grammar means that the following regular expression features are no longer supported in condition strings:

    • \c<letter> control code escape sequences, use \x<hex> instead

    • The \0 null escape sequence, - use \x00 instead

    • The [:d:], [:w:] and [:s:] character classes, use [:digit:], [:alnum:] and [:space:] instead respectively.

    • \<number> backreferences

    • (?=<subpattern>) and (?!<subpattern>) positive and negative lookahead

0.13 - 2018-04-02

Added

  • The Group data structure.

  • The groups list to the root of the metadata file format.

  • The group key to the plugin data structure.

Removed

  • The priority field from the plugin data structure.

  • The global_priority field from the plugin data structure.

0.10 - 2016-11-06

Added

  • The clean key to the plugin data structure.

  • The global_priority field to the plugin data structure.

  • The many_active() condition function.

  • The info key to the cleaning data structure.

Changed

  • Renamed the str key in the localised content data structure to text .

  • The priority field of the plugin data structure now stores values between -127 and 127 inclusive.

  • Regular expressions no longer accept \ as a directory separator: / must now be used.

  • The file() condition function now also accepts a regular expression.

  • The active() condition function to also accept a regular expression.

  • Renamed the dirty info data structure to the cleaning data structure.

Removed

  • The regex() condition function, as it has been obsoleted by the file() function’s new regex support.

0.8 - 2015-07-22

Added

  • The name key to the location data structure.

  • The many("regex") condition function.

  • The documentation now defines the equality criteria for all of the metadata syntax’s non-standard data structures.

Changed

  • Detection of regular expression plugin entries. Previously, a plugin entry was treated as having a regular expression filename if the filename ended with \.esp or \.esp . Now, a plugin entry is treated as having a regular expression filename if the filename contains one or more of :\*?| .

Removed

  • Removed the ver key in the location data structure.

Fixed

  • The documentation gave the values of the after , req , inc , tag , url and dirty keys as lists, when they have always been sets.

0.7 - 2015-05-20

Added

  • The message string substitution key, i.e. sub , in the message data structure.

  • Support for YAML merge keys, i.e. << .

Changed
